FRANKLIN P. BATES, OF INDIANAPOLIS, INDIANA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 690,391, datedJanuary 7, 1902.

Application iiled April 13, 1901. Serial No. 55,766. (No model.) i 'l To all whom, it may concern:

Beit known that I, FRANKLIN P. BATES, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to certain new and useful improvements in wrenches; and it consists in a new and improved form of construction of the same and will be hereinafter more fully set forth, and particularly pointed out in the claims.

The object of this invention is to simplify and to cheapen the construction of this particular type of wrench without sacrificing the strength or durability of the same. I attain this object by means of the construction of the wrench illustrated in the accompanying drawings, in which similar numerals of reference designate like parts throughout the sev? eral views.

Figure 1 is a side elevational view of a wrench embodying my invention. Fig 2 is a detail view of the screw and tang member thereof. Fig. 3 is an end'view of the same looking in the direction indicated by the arrow a. Fig. 4 is a similar end view of the same looking in the direction of the arrow b. Fig. 5 is a detail side view of the main member of the wrench and the tang-handle thereof, and Fig. 6 is 'an end view of the same looking in the direction of the arrow c.

The'wrench is or may be of the well-known type and is composed of a main member having the rectangular portion 1, the fixed jaw 2, the primary or main handle portion 3, the strap-fit 4, and the sliding jaw 5, provided with the retaining-bands 6 and 7, formed integral on said jaw 5 and which latter encircle the rectangular portion 1 of the main niember to guide said jaw 5 and to preserve its alinement with the fixed jaw 2 at all points throughout the scope of its path of adjustment. The fixed jaw 2, the rectangular body 1, the strap-lit 4, and the tang or handle portion 3, constituting the main 'member of the wrench, are formed in one integral piece.

The secondary member is composed of the handle or tang member 8, the strap 9, and the screw portion 10, all of which elements are constructed in one integral piece, and the said strap member is adapted to slip on and to accurately fit on the strap-fit 4.

In order to practice my invention, I first construct the main member having the iixed jaw 2, the rectangular portion 1, the strapt 4, and the tanger handle portion 3, all of which elements are forged or otherwise formed in one single integral piece. I next construct the sliding head 12 and form the retaining guide-straps 6 and 7 thereon, and said straps are constructed to receive the rectangular portion l of the main member to retain and to guide the head 12 thereon. A screwway 13 is now drilled or otherwise formed in said head-1.2,V and said wayis made parallel with the bearing-face of the head 12 and the rectangular portion 1 of the main member, and said screwway is of a diameter su ficiently large to permit the free entrance of the said screw 10. A transverse slit 14 is now cut at right angles with. the center line of .the screwway 13 a'nd is offa depth and width sufficiently large to permit the entrance and free working of the screw-nut 15 therein. The screw-nut 15 is -of av disk form and has its peripheral edge milled or knurled in the usual manner, and said nut is drilled centrally and threaded to freely receive the screw 10. I next insert the tang-handle end 3 of the main member into the straps 6 and 7 of the traversing head 12, with the face of the jaw 5 thereof directed toward the face of thefixed jaw 2, andmove said head 12 toward said jaw 2 till the said straps 6vr and 7 encircle the rectangular portion 1 of the main member of the wrench. I next construct the screw or secondary member, which is composed of the secondary handle tang end 8, the intermediate strap portion 9, which is adapted to encircle and iit on the strap-fit 4 of said main member, and the screw 10, which elements are formed in one integral piece. I next place the nut 15 in position in the receiving slot or slit 14, formed in the traversing jaw-head 12, then insert the end 16 of the tang-handle 3 into thel strap 9 of the secondary or screw member, so that the screwreceiving Way 13 of said head 12 will be directly opposite the screw 10, and slide said secondary or screw member on said tang 3 of said main member till the strap members 9 encircles the strap-fit 4 and till the said end IOS 16 of the tang 3 laps the lap end 17 of theA member composed of a fixed jaw, a rectangular portion and a tang portion formed in one integral piece, and a sliding jaw, of a secondary member composed of a screw portion and a tang portion integral on said screw portion, and means for securing said secondary member to said main member.

2. In a wrench, the combination with a main member composed of a fixed jaw, a rectangular portion and a tang-handle, all formed in one integral piece, and a sliding jaw, of a secondary member composed of a screw, an intermediate retaining-strap, and a tang-handle all formed in a single integral piece,said secondary member applied to said main member so that the retaining-strap of the former member encircles said main member atapoint above the tang-handle thereof, and means for retaining and securing said secondary member in position on said main member.

V 3. In a wrench, the combination with a main membercomposed of a fixed jaw, an intermediate rectangular portion and a tang-handle all formed in one integral piece, and a sliding j aw on said main member, of a secondary fixed or stationary screw member, and means forsecuring said screw member to said main member so that the screw will be in position relative to said sliding jaw.

4. In a wrench, the combination with a wrench composed of a main member having a fixed end jaw, and a sliding jaw on said main member and provided with a screwway, and a tang portion formed on the end of said main member, of a secondary member having a screw end, a handle end, and an intermediate strap portion, which member, after placing said sliding jawin position on said member, is applied to said main member so that the retaining strap thereof encircles said main member, and said screw enters the screwway of said jaw-head. Y

5. The combination with a wrench composed of a main member having a fixed jaw, a rectangular portion, a strap-lit, and a handle portion, of a sliding jaw-head, a secondary or screw member having a screw, a handie and an intermediate retaining-strap, said handle members having their ends halved or divided so that when said secondary member is applied to said main member to place said screw in position, said handles will lap at their endsand suitable means for ksecuring the lapped ends of said handles together.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRANKLIN P. BATES.
